How will you describe the sequence of oxygen, carbon dioxide, and blood flow in your own words?
Answers
Answer: Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. ... Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
Explanation:
The sequence of oxygen, carbon dioxide, and blood flow can be in following ways :
1. We inhale air and it passage through nasal passage and reaches the lungs.
2. The oxygen from air is separated and combine with haemoglobin in blood and transported to different parts of the body.
3. Oxygen is used up by the living cells for metabolism and carbon dioxide is produced as by products.
4. Carbon dioxide is transmitted to the veins and carried back to the lungs. The lungs expel carbon dioxide through same nasal passage and the process is again repeated.
